[n_m3u8dl-re] audio-video sync

[eldepor]

Im testing --live-pipe-mux True --live-real-time-merge False and so far its giving properly synced output. At least in mp4 format with RE_LIVE_PIPE_OPTIONS:
-reset_timestamps 1 -movflags +faststart

EDIT: nevermind. I`ll keep investigating

When --live-pipe-mux is set, the --live-real-time-merge is effectively ignored, so its value has not been applied

The audio sync actually depends only on the starting point. When the starting points of the video and audio do not align, the audio becomes out of sync. However, when you set --live-real-time-merge True and unset --mux-after-done, the audio will sync no problem. Because in this case, the stream’s starting point is the moment the streamer begins broadcasting, that ensuring that both the audio and video have the correct timestamps. The current focus is on how to make FFmpeg to automatically offset to the correct time.
